Horrendous experience. I wanted a temporary SIM while visiting the USA for 1 week. I went to the AT&T store on 1011 W 5th St, Austin, TX and specifically explained I wanted a SIM that was active for 1 month or less. I explained this very clearly 2 times. Now they have decided to keep billing me. Yet, as I am not a US resident, and have no official account, it appears impossible to cancel my account with them.Have tried numerous times to get through to their customer service but it's a truly morale shattering experience, one that makes you question our very existence on this earth. How can companies treat customers like this and not be shut down? Scandalous and infuriating. Deplorable service and those working for the company should be utterly ashamed.
